721267 ÷ 76 
The aim is to understand the frequency of 76 in 721267.

On to step 1:
The number 76 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 76

Going ahead to step 2:
When dividing 72 by 76, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 76

Let's proceed to step 3:
If we divide 721 by 76, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 9.0
If we take 684 away from 721, we end up with 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 76

Advancing to step 4:
When dividing 372 by 76, we get 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 94.0
If we subtract 304 from 372, we get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 76

Advancing to step 5:
When dividing 686 by 76, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 949.0
The remainder is 2 after subtracting 684 from 686.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 76

Let's proceed to step 6:
The number 76 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 9490.0
Deduct 0 from 27 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
If we divide 270 by 76, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 9490.3
Subtracting 228 from 270 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
76 can be fit into 420 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 9490.35
The remainder is 40 after subtracting 380 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
400 divided by 76 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 9490.355
If we take 380 away from 400, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 9490.355, and the remainder is 0.002.
